Thickness t terminology ASME Sec I A-250.2.3

Thickness t terminology ASME Sec I A-250.2.3

Thickness t terminology ASME Sec I A-250.2.3

(OP)
Please refer page 205 of ASME Sec I A 250.2 terminology, ASME Sec V T-434.5.1 h) on page 47, ASME SEc I Fig PG-42.1 on page 36. Issue: What is the thickness t as referred to in A-250.3.3 and A-250.3.7, whether it includes weld reinforcement? When we define t, is it the least of thickness of weld or the thinner section of the materials? I like to consider it as only the weld thickness of thinner material with the reinforcement thickness as specified by code ASME Sec I PW 35.1 on page 104.

RE: Thickness t terminology ASME Sec I A-250.2.3

(OP)
I list here the codes we referred and could not clearly identify how to calculate the weld thickness solely for inspection purpose because
a) maximum and allowable reinforcements are not defined
b) how to measure thick and thinner section welds are not known
c) whether the thickness of weld or plate includes crown and root penetration is not known

Page 76 of ASME B31.3 Table 341.3.2; ASME Sec VIII Div 1 page 150 UW-51; ASME Section IX QW 191.2.3; ASME Sec I A -250.2.3 Page 205; ASME Sec V Fig T-434.2.1 page 47 Notes (h)
Another funny inconsistency is the same notation t for minimum wall thickness and for weld thickness is used in ASME Sec I and in others!
